Hinako, a sober glasses OL, is cheated on by her boyfriend Daiya, who has been living together for 3 years and is about to get married, and the moment she nails a straw doll at the edge-cutting shrine with anger, lightning strikes directly! When you wake up, there is a grim reaper in the form of a clown. From him, Hinako is given the ability to transform into an unparalleled beauty only during the night, and while drowning in the pleasure of going back and forth like revenge for her life, which she had previously had the motto of "sober and calm", she meets Ryota, a prince who thinks "This time he is a man of destiny!" But is such a double life really, really, okay!?
